Engine variable valve timing (VVT) solenoid 31480440 31480441 Engine camshaft cylinder head solenoid valve for Volvo
Product Description:
Camshaft electromagnetic valve
OE NO.: 31480440 31480441
Applicable vehicle type: For Volvo
The camshaft solenoid valve is the core executive component of the modern engine VVT (Variable Valve Timing) system. It achieves real-time adjustment of the camshaft phase by precisely controlling the hydraulic oil circuit, thereby optimizing the engine's power performance, fuel economy, and emission performance.
When the camshaft solenoid valve fails, typical symptoms include:
1. Difficulty starting: The solenoid valve cannot normally switch the oil circuit, resulting in the camshaft being in an incorrect phase.
2. Weak acceleration: The drain hole is closed, causing the regulator to malfunction and the valve timing to be unable to be optimized.
3. Unstable idle: Miscalibrated phase adjustment causes fluctuations in intake air volume, leading to engine vibration similar to a misfire.
4. Easy stalling: During driving, the solenoid valve sticks or suddenly loses power, causing the engine to lose timing regulation.
5. Malfunction indicator light illumination: The ECU detects a mismatch between the position sensor signal and the command, storing a fault code.
6. Increased fuel consumption: Reduced combustion efficiency leads to deteriorated fuel economy.
7. Excessive emissions: Emissions of pollutants such as NOx and HC exceed the limit values.
